Meade 777 Off-Axis Guider

The Meade #777 Off-Axis Guider allows the photographer to monitor the telescope’s tracking and ensure that it remains perfectly positioned on the object being photographed. Such capability is pivotal during long-exposure astrophotography. Like the T-Adapter, the Guider couples the camera body to the telescope. It also causes a small amount of the guidestar’s incoming light to be diverted at a right-angle, where the star’s position can be examined for tracking errors with the crossline pattern of the PL9mm Illuminated Reticle Eyepiece or other guiding devices. Any necessary position corrections can then be made using the telescope’s drive systems. The #777 works with any LX-Series telescope or other Schmidt-Cassegrain. Use with the appropriate T-Mount, ordered separately, for your 35mm camera brand. Note: The #777 Off-Axis Guider also works with ED Apochromatic Refractors. Just add the Universal Thread Adapter along with the T-Mount to the Guider to begin your photographic guiding applications.
